Joe,this is off topic kinda on that but did you find any reason or paper work on why the heads and oil pan have been taken off before that part scared me on a lo mileage 8V92 engine ? Low oil pressure and overheating will shut a DDEC down
I am just curios why the heads and pan were remove and both heads were removed
Not sure if you have confused Joe(s) or buses. But to directly answer your question. This bus had a complete rebuild about 20,000 miles ago Or when it only had about 80,000 miles on it.
According to the PO it was right after he purchased the coach. He was on I-70 west bound out of Denver and he drive it till it seized. Stewart and Stevenson did the rebuild. They did not try and rod the radiator. New radiator from prevost. Blamed on the use of the wrong coolant. All 8 cylinder kits. new main and rod bearings. new injector assembly. Below is the summary from the bill. (yes I asked and got papers on the advertised rebuild). I never got a clear answer as to why the DDEC did not interlock it down but was told all those systems work now.
Engine runs good. No leaks as it sits and it did not burn/leak any oil on the 1000 mile trip.
